If x is 2+ root 3 then find (x^2+1/x^2) (x^2-1/x^2)

Here  x=2−3–√ ……………………………………(1)

Hence  12−3√=12−3√⋅2+3√2+3√=2+3–√ (2)

From (1) and (2) we get  x+1x=4 ……………………………(3)

and  x−1x=−23–√ …………………….………(4)

From (3) and (4) we get  x2−1x2=(x+1x).(x−1x)=−83–√.

Hoped I helped

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
